Arcane lock, also known as wizard lock,[5][10] was an arcane abjuration (formerly alteration)[5] spell that allowed the caster to lock closed entryways.[3]


By touching a closed door, window, gate or other entryway, the caster would lock it.[3] The caster could pick a creature type or even a password that would allow them to open the locked entryway.[citation needed]

Unwanted visitors could enter only if the object was broken or if the spell was suppressed. The spell could be suppressed by a knock or dispel magic spell[3] and the suppression lasted for 10 minutes. When the spell was active,[citation needed] the lock was harder to pick or break.[3]


The spell required verbal and somatic components and gold dust worth 25 gold pieces.[11][3]


The spell was attributed to Netherese arcanist Ptack in −502 DR and was originally called Ptack's locking.[1]
